What is the problem this feature will solve?

When there are a lot of small quick-fixable issues in someone else's code, it's inpractical and tedious to fix them all one by one manually, even with hotkeys.

Even Ctrl+A Ctrl+. combo shows a whole list of Quick Fixes that still disappears on every click or enter and displays all of the quick fixes wothout any "Apply all" buttons not other bulk actions.

What is the feature you are proposing to solve the problem?

Add / implement / enable "Fix All" / "Apply all Quick Fixes" action.

What alternatives have you considered?

Not sure if there are any, open to suggestions.
